RELATED APPLICATION

This application claims priority to provisional patent application U.S. Ser. No. 62/755,273 filed on Nov. 2, 2018, and is a continuation of U.S. Ser. No. 16/539,617 filed on Aug. 13, 2019, the entire contents of which are herein incorporated by reference.

BACKGROUND 1. Field of the Invention

The present invention relates to a smoking article machine for forming a plant material smoking article.

2. Description of Related Art

The popularity and stigma of smoking tobacco has recently been negatively affected, as more carcinogenic and health data is publicly published. This has caused the popularity of smoking traditional tobacco cigarettes to decline greatly in popularity. Furthermore, recent spikes in taxes on tobacco and tobacco affiliated products have also driven down the consumer popularity of buying traditional tobacco cigarettes. Consequently, it is now more popular and economically viable to produce smoking articles comprising a plant material or a mixed plant material, such as cannabis, to appeal to the consumer and to reduce the realized cost to the consumer.

Additionally, known cigarette making machines are behind modern advancements in technology. Traditional curing and manufacturing processes related to tobacco based smoking articles vary greatly when compared to the curing, processing, and manufacturing processes of other plant material smoking articles. Variable factors of controlling tobacco particle size, compression of tobacco within the combustible material, and filter insertion do not provide the same desired result when dealing with plant materials other than tobacco.

Furthermore, smoking articles need a high level of uniformity for retail packaging and consistency of a deliverable product to the consumer. Reliability of traditional machines is known to be low, especially as the combustible material of most smoking articles are prone to folding, shearing, and deforming through the cigarette forming process. When a break in the production cycle does occur, the entire cigarette forming process stops, and successive parts of traditional forming machines need to be reconfigured, replaced, or reset to restart the production of smoking articles forming process. As previously stated, the occurrence of this stoppage is only exponentially increased as plant material other than tobacco is added to the tobacco or substituted for tobacco.

Consequently, different methods and machines are necessary to prepare plant material for forming and to form plant material smoking articles. Furthermore, different control systems utilizing temperature controls, humidity control, and inspection controls are needed to optimize the forming of plant material smoking articles and the surrounding environment that the forming machine and method occur in.

Exemplary prior art for tobacco cigarette forming machines includes US10/645,996, to Hancock et. al., which claims an entrance cone for creating a tobacco cigarette, as shown in FIG. 12 and FIG. 13, that is specifically adapted for the rolling of shredded tobacco material. Similarly, another exemplary prior art having forming machines can be viewed in U.S. Ser. No. 09/776,776, to Okumoto et. al., which claims a molding bed of a compression molding apparatus for molding paper around shredded tobacco. These machines would prove to be ineffective when used with other materials outside of shredded tobacco. This is due largely in part to the material properties of shredded tobacco having low adherent properties. These low adherent properties allow for easy movement of shredded tobacco during forming as the paper is abruptly closed around the shredded tobacco and the shredded tobacco is free to move within the paper as needed.

Secondly, the moisture content desired in shredded tobacco is much lower than other plant materials to be smoked, such as cannabis. On top of differing moisture content desired in the resultant smoking article, tobacco cigarette forming machines have no means or compensation for removing dense plant materials such as plant seeds and stems that may enter the machine.

This lack of compensation for removing dense materials is largely due in part to the fact that tobacco seeds are very small in size and are much smaller in size than strands of shredded tobacco themselves. Although tobacco seeds are commonly sorted from tobacco leaves prior to being formed into a cigarette, some seeds still find passage into traditional forming machines. Typical tobacco seeds are estimated to be less than 0.01-0.02 inches in diameter. Wherein other plant materials, such as cannabis, typically have seed sizes between 0.06-0.20 inches in diameter. The sheer size of the tobacco seeds allows them to easily be feed through traditional forming machines without breaks in production. Feeding plant material other than tobacco into and running exemplary traditional tobacco cigarette making machines, such as those taught by Hancock et. al. and Okumoto et. al., would result in failure of the machines as seed or stems were attempted to be formed into a cigarette. The seeds and stems would puncture the paper of the cigarette, causing blockage in multiple areas of the machines and would be physically incapable of fitting within the cigarette. In possible situations wherein all dense material is removed or processed from plant material other than tobacco, the exemplary prior art taught above and similar machines would still result in failure due to variability of adherent properties of plant material other than tobacco and the lack of uniformity in processed plant material other than tobacco. The variability of plant material other than tobacco should be accounted for in the forming of cigarettes and the like.

Secondly, consumers commonly desire to smoke plant material other than tobacco for reasons other than taste or nicotine commonly added to tobacco cigarettes. For example, traditional tobacco forming machines are not properly adapted to retain trichomes or other fine outgrowths of various plant materials during the forming of the cigarette. Traditional machines for making cigarettes lack these capabilities to the fact that tobacco leaves do not have trichomes or other fine and delicate plant properties that need to be properly accounted for during the forming of cigarettes and similar smoking articles.

Exemplary mechanisms for feeding tobacco into cigarette forming machines can be seen in the exemplary prior art such as U.S. Pat. Nos. 1,645,067 and 1,817,319, to Muller, which claims both a tobacco spreading machine and a tobacco spreader for cigarette machines respectively. Both exemplary tobacco material related machines claimed by Muller illustrate drums for feeding shredded tobacco into a cigarette forming machine. These machines and the like are not designed for removing dense materials commonly found in other plant materials because they are optimized for only moving shredded tobacco.

An improved system is needed for creating plant material smoking articles comprising largely plant material other than tobacco. An improved system is needed having dense material separating means, mitigation of accumulation plant material throughout the system, assemblies and methods designed for preserving trichomes and other fine outgrowths of various plant materials, and gradual forming means to slowly compress and form plant material within a combustible material when the plant material to be formed has high adherent properties.

SUMMARY

The current invention is directed towards a smoking article machine for producing plant material based smoking articles. The machine is designed to overcome the pitfalls of traditional tobacco processing and cigarette forming machines. Components of the machine carefully guide desirable plant material through a forming process carried out by the smoking article machine.

An object of the present invention is to provide a smoking article machine for forming plant material smoking articles optimized for the minimal accumulation of plant material within and between the various assemblies and components of the smoking article machine.

Another object of the present invention is to provide a wrapping rate of a plant material within a continuous stream of paper that is gradual and slow by varying adjustable means and at least one adjustable guide that is elongated in view of traditional forming garnitures.

Another object of the present invention is to preserve fine outgrowths of various plant materials by providing configurable material assemblies and feeding assemblies for preserving trichomes and fine outgrowths of various plant materials.

In order to do so, a machine for making plant material smoking articles is provided having a feeding assembly that is configured to feed plant material to a combustible material rolling assembly. The combustible material rolling assembly includes a continuous stream of paper and a forming chute having a semispherical channel at a length and at least one adjustable guide. The combustible material rolling assembly is configured to roll the plant material in the continuous stream of paper at a wrapping rate within the semispherical channel to make at least one plant material smoking article. In some embodiments, the feeding assembly is either driven via gravity or a pneumatic delivery system. In one embodiment, at least one adjustable guide includes a tapered conical guide configured to additionally adjust the wrapping rate.

Referring now to FIGS. 1-5, various views of a smoking article machine 350 are illustrated. The smoking article machine 350 is configured to form a plant material smoking article 485 from a plant material 100. The forming process 345 will be discussed below.

Preferably, the plant material 100 is cannabis. Alternatively, the plant material 100 comprises by way of non-limiting example, a tobacco plant, a clove, a damiana, a hash, a spice, a herb, a flowering plant, an artificial flavoring, a bark, a bud, or a root. In some embodiments, the herb includes of at least one the following plant families, by way of non-limiting example, the Cannabaceae plant family, the Malvaceae plant family, the Apiaceae plant family, the Lamiaceae plant family, and the Asteraceae plant family.

The plant material 100 comprises a desirable plant material 125 and an undesirable plant material 126. In the preferred embodiment, the plant material 100 is cannabis, and the desirable plant material 125 includes the smokable portions of the cannabis, including but not limited to the calyxes (buds), resin, and to a lesser extent, leaves. Conversely, the undesirable plant material 126, for cannabis, includes but is not limited to roots, stems, branches, leaves, and seeds. As well known in the art, the plant material 100 will go through standard handling procedures after harvesting, including but not limited to curing, trimming, and grinding, wherein some of the undesirable plant material 126 will already be separated from the desirable portions of the plant material 100. In some embodiments, the plant material 100 will go through a plant material preparation process 101 which will be discussed in greater detail below.

It is a particular advantage of the present invention, to provide a plant material separator 605 that is configured to separate the undesirable plant material 126 from the desirable plant material 125 during operation. This will be discussed in greater detail below. As one in the skill in the art may formulate, the invention may be modified for the use of other plant materials, as discussed above, however the machine, and elements of the machine, have been optimized for use with cannabis providing an improved smoking article machine for use with cannabis compared to the machines of the prior art.

In one embodiment, the smoking article machine 350 includes at least one of the following assemblies: a control assembly 432, a pneumatic plant material assembly 325, a gravity plant material assembly 326, a combustible material rolling assembly 330, a rotational transfer assembly 430, a filter assembly 335, and an inspection assembly 340. Each assembly will now be described in detail below.

In one embodiment, the gravity plant material assembly 326 comprises a plant material hopper 355, a plant material separator 605, and a gravity feeding assembly 645. In one embodiment, the plant material hopper 355 is configured to receive the plant material 100 and feed the plant material 100 to the plant material separator 605. In other embodiments, the smoking article machine 350 is configured to have a pneumatic plant material assembly 325 and a pneumatic feeding assembly 646. In one embodiment, the gravity plant material assembly 326 and the pneumatic plant material assembly 325 can be configured to include an enclosure 356 surrounding the plant material 100 processed within.

Been seen in FIGS. 6-7, the plant material separator 605 is configured to separate the undesirable plant material 126 from the desirable plant material 125. In one embodiment, the plant material separator 605 comprises a first roller 615, a second roller 610, a third roller 620, and a fourth roller 625. The first roller 615 having a first diameter configured to rotate in a counter-clockwise direction at a first speed, the second roller 610 having a second diameter configured to rotate in a counter-clockwise direction at a second speed, the third roller 620 having a third diameter configured to rotate in a counterclockwise direction at a third speed, and the fourth roller 625 having a fourth diameter configured to rotate in a clockwise direction at a fourth speed. The first roller 615 is configured to thin out the plant material. The first roller 615 and the second roller 610 are positioned approximate to the plant material hopper 355, such that as the plant material 100 passes through the plant material hopper 355, the plant material 100 is pressed between the first roller 615 and the second roller 610 separating the plant material 100 into the desirable plant material 125 and the undesirable plant material 126, sending the plant material to a first directional path. Next, the plant material is compressed via comb 650 into position, wherein the plant material is fed to the fourth roller 625, which spins the plant material to the third roller 620, wherein the third roller 620 is configured to redirect the undesirable plant material 126 a second directional path. In some embodiments, a portion of the thinned out plant material from the first roller 615 travels along a third directional path, wherein the third directional path is substantially parallel to the first directional path and the thinned out plant material is desirable plant material.

Advantageously, a catch depository 600 is positioned to catch the undesirable plant material 126 from the second directional path within the enclosure 356. The catch deposit may be adjoined, slidably engaged, or hingedly connected to the enclosure 356. In one embodiment, the comb 650 includes a series of teeth aids and guides the plant material 100 through the plant material separator 605. In some embodiments, the comb 650 is further designed and sized to substantially match a gap between any of the pluralities of protrusions 621 on any of the rollers of the smoking article machine 350. In some embodiments, the comb 650 is adjustable. In some embodiments, the comb 650 is oriented in a fixed position. In some embodiments, the comb is 650 configured to compact the desirable plant material against the second roller.

The details of the undesirable plant material 126 and the desirable plant material 125 were previously discussed for the preferred use of cannabis. The material separator takes advantage of the properties and characteristics of the plant material 100. For instance, the undesirable plant material 126, such as stems and seeds, is denser than the desirable plant material 125, such as the ground bud. Thus, the undesirable plant material flies further when passing through the rollers and more specifically the third roller 620 flicks or displaces the undesirable plant material into the catch depository 600. The catch depository 600 is removable from assembly 430 and the enclosure 356 such that the undesirable plant material 126 may be discarded or used in other applications. In one embodiment, the catch depository 600 is a removable drawer slidably engaging the enclosure 356.

Best seen in FIGS. 7-8, each of the rollers include a plurality of protrusions 621. The first roller 615 and the second roller 610 include a first plurality of protrusions 635 and a second plurality of protrusions 636, respectively. The third roller 620 and the fourth roller 625 include a third plurality of protrusions 621 and a fourth plurality of protrusions 622, respectively. It should be understood, that these are merely examples, and the protrusions 621 may be selected from a protrusion set essentially consisting of: a pointed protrusion, a cylindrical protrusion, a tapered cylindrical protrusion, a tab, a threaded protrusion, a brush, or any combination thereof. The protrusions should be selected for the desired function. As an example, the first plurality of protrusions 635 and the second plurality of protrusions 636 are sharp pointed protrusions, such that when in combination with the diameter and rotation of the first roller 615 and the second roller 610 rotating at the first and second speed respectively, the sharp pointed protrusions further grind the plant material 100, separating the seeds and stems from the smokable bud or flower material. As well known in the art, smoking the seeds and stems leads to undesirable flavors and harsh smoke, which is undesirable for the user.

As previously discussed, the undesirable plant material 126 is collected in the catch depository 600, preventing the undesirable plant material 126 from being used in the further processes and assemblies of the machine such that the smoking articles produced will be comprised of substantially the desirable plant material 125.

In the gravity plant material assembly 326, the desirable plant material 125 from the first directional path and the third directional path leads to the gravity feeding assembly 645, and more specifically a first feed belt 365, wherein the first feed belt 365 directs the desirable plant material 125 to the gravity feeding assembly 645, which in turn supplies the desirable plant material 125 to the combustible material rolling assembly 330. The first and third directional paths are in a generally downward direction. Best seen in FIG. 10, the gravity feeding assembly 645 utilizes gravity to feed the plant material 100 to the combustible material rolling assembly 330. In alternative embodiments, the pneumatic feeding assembly 646 utilizes a pneumatic delivery system. However, the gravity feeding assembly 645 is preferred. In some embodiments, the gravity feeding assembly 645 and/or the pneumatic feeding assembly 646 further comprises a plurality of rollers, guides, combs, blades, brushes, or other elements configured to guide the plant material 100, as well as control the delivery rate of the plant material 100 to the combustible material rolling assembly 330.

Referring now to FIGS. 11-17 and 23, the combustible material rolling assembly 330 is illustrated and described. The combustible material rolling assembly 330 is configured to roll the plant material 100 in a continuous stream of paper 396 at a wrapping rate to make at least one smoking article. The continuous stream of paper 396 is fed by the second feed belt 380. In one embodiment, the combustible material rolling assembly 330 comprises the continuous stream of paper 396, a forming chute 660, and at least one adjustable guide 390. The forming chute 660 is a plate having a semispherical channel 670 having a predetermined length in the center of a top surface of the plate. In one embodiment, the predetermined length is at least 3.5 inches. In some embodiments, the predetermined length is at least the length of the at least one smoking article. In some embodiments, the predetermined length is at least 7 inches.

In one embodiment, the at least one guide is a left guide mold 525, a right guide mold 526, and a tapered conical guide 665. The tapered conical guide 665 includes a conical angle 675. In some embodiments, the conical angle 675 is adapted for use with specific types of the plant material 100. In one embodiment, at least one adjustment device 530 is positioned on the plate of the forming chute 660 on both sides of the semispherical channel 670. In one embodiment, the at least one adjustment device 530 is positioned on the at least one adjustable guide 390. In one embodiment, the at least one adjustment device 530 is selected from a: a screw, a worm drive, a lever, a clamp, a handle, a knob, and a gear. The at least one adjustable guides 390 is positionable at various locations along the forming chute 660 such that the wrapping rate of the roll via the continuous stream of paper 396 may be adjusted. More specifically, the at least one adjustable guide 390 is configured to be adjusted to a first variable pitch 531 affecting the characteristics of the plant material smoking article 485. The first variable pitch 531 defined by a first position of the at least one guide in relation to the semispherical channel 670 via the at least one adjustment device 530. The tapered conical guide 665 of the at least one guide is configured to be adjusted to a second variable pitch 532 affecting the characteristics of the plant material smoking article 485. The second variable pitch 532 defined by a second position of the tapered conical guide 665 in relation to the semispherical channel 670 via the at least one adjustment device 530. The first variable pitch 531 and the second variable pitch 532, via the at least one guide, adjusts the wrapping rate, which is defined as the rate at which the smoking article is rolled into a cylinder. Advantageously, the wrapping rate and wrapping angle are optimized for use with the plant material 100 being cannabis.

In some embodiments, the at least one adjustable guide 390 of the combustible material rolling assembly 330 can be made of or coated in at least one mold material of a mold material set consisting of: a plastic, a thermoplastic material, a polyoxymethylene material, a metal material, a resin material, a polytetrafluoroethylene material, a polyamide material, a polyimide material, a nylon material, a acetal material, a polyester material, a polyetheretherketone, a polyphenylene sulfide material, a ceramic material, a polyethylene material, a Teflon material, a polysulfone material , a polyimide material, a polyphenols material, a phenol material, and a polyphenol material. Advantageously, the materials of the mold material set of the current exemplary embodiments are chosen for their low kinetic and static friction coefficients. In some embodiments, the mold materials of the mold material set have a friction coefficient between 0.02 to 0.8.

The at least one adjustable guide 390 is adjusted to change at least one of the following plant material smoking article's characteristics: diameter of the plant material smoking article 485, density of the plant material smoking article 485, the desirable plant material 125 compression variability between different batches of the desirable plant material 125, a taper of the plant material smoking article 485, and changing friction coefficients between different continuous stream of paper 396 feed by the second feed belt 380.

During operation, the plant material 100 via the gravity feeding assembly 645 or the pneumatic feeding assembly 646, is distributed at a predetermined rate on the continuous stream of paper 396, then the paper 396 is rolled into cylinder (a smoking article) via the semispherical channel 670 and the at least one adjustable guide 390. In one embodiment, the second feed belt 380 transfers the paper 396 throughout the process. An adhesion means 405 is configured to seal the smoking article into the cylindrical shape as well known in the art by attaching the continuous stream of paper 396 on to itself. The smoking article is then cut into multiple smoking articles each at a second length via a first cutting device 420 (not shown). The smoking article is then transferred to the rotational transfer assembly 430.

In some embodiments, the adhesion curing means 415 comprise of at least one of a curing set consisting of: a heater, a visible light source, a non-visible light source, a blower, a laser, a thermoelectric device, and a heat lamp. In some embodiments, the adhesion means 405 include at least one of an adhesion set consisting of a weld, an adhesive, a fold, and a fusion process.

In some embodiments, the first cutting device 420 (not shown) is communicatively coupled with the hardware control of the control assembly 432. In some embodiments, the first cutting device 420 is carried out at a predetermined, random or variable rate, speed, or time period. In some embodiments, the first cutting device 420 is a least one member of a cutting set consisting of: a waterjet device, a whip, a string, a heated string, a laser device, a one-sided blade, a round blade 580, a heated blade, and a wheel 690 driven by a motor assembly 640.

Now referring to FIGS. 18-21, the rotational transfer assembly 430 is illustrated. The rotational transfer assembly 430 is configured to transfer and rotate the smoking article to the filter assembly 335 from the combustible material rolling assembly 330. The rotational transfer assembly 430 comprises a transfer wheel 690, a plurality of transfer elements 685, and a wheel control drive assembly 700. The transfer wheel 690 is configured to rotate in a rotational direction 710 at a rotational speed. In one embodiment, the plurality of transfer elements 685 are attached and positioned radially to the transfer wheel 690, each transfer element of the plurality of transfer elements 685 is configured to receive the smoking article traveling in a first direction 680 at a linear speed from the combustible material rolling assembly 330. In one embodiment, an air component set is provided, wherein the air component set is configured to vacuum and retain the smoking article on the plurality of transfer elements during rotation. In one embodiment, the air component set is at least one of: an air suction device, a blower device, an air compressor, a pneumatic delivery system, a vacuum, and a fan.

In one embodiment, each transfer element of the plurality of transfer elements 685 is aligned parallel to the first direction 680 continuously during rotation. Further, each transfer element includes a semispherical shaped engagement surface 715 configured to engage the smoking article. In one embodiment, the engagement surface has an arc radius approximate to an arc radius of the smoking article. In some embodiments, a plurality of apertures is arranged upon the semispherical shaped engagement surface 715 and extended through the plurality of transfer elements 685. The plurality of apertures in fluid connection with the air components set 360. The wheel control drive assembly 700 is configured to control the rotational speed via the motor assembly 640, gears, and the control assembly 432. It should be understood that other components may be provided in the wheel control drive assembly 700 for operation. The wheel control drive assembly 700 enables the rotational speed to be synchronized with the linear speed such that each transfer element is in the perfect position to accept a new smoking article via the combustible material rolling assembly 330. In the preferred embodiment, each transfer element of the plurality of transfer elements 685 is configured to engage at least two smoking articles.

Referring now to FIG. 24, components of the filter assembly 335 are described.

As cannabis plant material is the preferred plant material, it should be understood that the plant material 100 may be subjected to federal and/or state regulations. Thus, depending on the regulations certain restrictions will be adhered to without departing from the spirit and scope of the invention. For instance, federal law now allows certain low-THC varieties of cannabis to be classified as “hemp,” which qualifies for regulatory allowances not available for other varieties of cannabis. Products, whether recreational or industrial, derived from such low-THC varieties of cannabis are commonly known as hemp products. Thus, a cannabis smoking article made from a low-THC variety of cannabis may be called a plant material smoking article 485, wherein the cannabis has a THCA, DELTA-9 THC, THC, TOTAL THC content or any combination thereof that is equal to or less than 0.3% by weight. One skilled in the art of cannabis cultivation and/or the study of cannabis will recognize that cannabis content limitations, concentrations and classifications potentially utilized with the present invention are constantly changing and re-configurable to match current state, federal and international laws and regulations.

The present disclosure includes that contained in the appended claims as well as that of the foregoing description. Although this invention has been described in its exemplary forms with a certain degree of particularity, it is understood that the present disclosure of has been made only by way of example and numerous changes in the details of construction and combination and arrangement of parts may be employed without departing from the spirit and scope of the invention.

All references throughout this application, for example patent documents including issued or granted patents or equivalents, patent application publications, and non-patent literature documents or other source material, are hereby incorporated by reference herein in their entireties, as though individually incorporated by reference, to the extent each reference is at least partially not inconsistent with the disclosure in the present application (for example, a reference that is partially inconsistent is incorporated by reference except for the partially inconsistent portion of the reference).

Any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specified function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. § 112, ¶ 6. In particular, any use of “step of” in the claims is not intended to invoke the provision of 35 U.S.C. § 112, ¶ 6.
